The Binding of Different Lectins on Peripheral Blood Mononuclear Cells from Patients with Chronic Inflammatory and Malignant Diseases

Peripheral blood mononuclear cells from patients with multiple myeloma, gastrointestinal tumors, and inflammatory bowel disease were analyzed for binding of various lectins. The results demonstrated that in most of the patients with multiple myeloma a significantly increased percentage of cells positive for Lotus tetragonolobus agglutinin (LTA), peanut agglutinin (PNA), soybean agglutinin (SBA), and wheat germ agglutinin (WGA), and a decreased number of Agaricus bisporus agglutinin (ABA) positive cells were present as compared to a normal control group. This could not be shown in malignant or inflammatory disorders of the gastrointestinal tract where only some patients exhibited an increased PNA and LTA binding, respectively. Patients with the systemic malignant disease differed from patients with solid localized tumors by a significantly altered number of ABA, LTA and SBA-positive peripheral blood mononuclear cells. Double fluorescence studies using monoclonal antibodies and lectins revealed that most of the cells expressing receptors for ABA had also receptors for OKT3, whereas most of the cells with receptors for LTA, PNA SBA, and WGA were found to be positive for OKM.

不同用量的吴茱萸炮制黄连后成分的比较

目的 考察不同用量的吴茱萸炮制黄连对小檗碱的影响以及英黄连中吸收吴茱萸成分的情况。方法 以小檗碱、吴茱萸碱、吴茱萸次碱为指标，采用高效液相色谱法测定黄连，吴茱萸，10％，20％，30％，40％，50％英黄连中的成分含量。结果 黄连用吴茱萸炮制后小檗碱的含量减少，20％，30％英黄连中小檗碱的含量较高；萸黄连中确实吸收了吴茱萸中的成分。结论 吴茱萸炮制黄连的用量以20％为宜。     

黄花败酱的化学成分研究

目的：对黄花败酱的化学成分进行研究。方法：采用乙醇提取,溶剂萃取,硅胶柱层析,重结晶等从败酱科植物黄花败酱的全草中提取分离活性成分,通过波谱解析及化学方法进行结构鉴定。结果：自黄花败酱醇提物中分得8个化合物。结论：除文献报道过的齐墩果酸（oleanolic acid),东茛菪素（scopoletin),β－谷甾醇（β－sitosterol)和β－胡萝卜甙（daucostarine)外,还首次从黄花败酱中分到2α－羟基齐墩果酸（2α－hydroxyoleanolic acid),2α-羟基乌苏酸（2α－hydroxyursolic acid),齐墩果酸－3－O－β－D－吡喃木糖苷（oleanoliic adic-3-O-β-D-xylopyranoside)和3,4－二羟基苯甲酸（3,4－dihydroxybenzoic acid)。     

Antitumor activity of polysaccharides isolated from Patrinia heterophylla

The research investigated the effect of Patrinia heterophylla Bunge (Valerianaceae) polysaccharides (PHB-P1) on U14-bearing mice. The tumor weight of mice treated with PHB-P1 (30, 60?mg/kg body weight) was significantly lower than that of the control group, a decrease of serum lactate dehydrogenase (LDH) activity was observed, and the serum alkaline phosphatase (AKP) level was increased slightly. The number of apoptotic tumor cells was significantly increased in the mice by treatment of PHB-P1 (30, 60?mg/kgbw). Cell cycle analysis showed the accumulation of tumor cells in the G2/M phase and a relative decrease of the S phase. By the immunohistochemical analysis, PHB-P1 (30, 60?mg/kgbw) might up-regulate the expression of p53 and Bax, and significantly inhibited the expression of Bcl-2 in tumor tissues. In conclusion, PHB-P1 could inhibit tumor growth and induce tumor cell apoptosis.
